Create a web page presentation using R Markdown that features a plot created with Plotly. Using the “mtcars” dataset. The data was extracted from the 1974 Motor Trend US magazine, and comprises fuel consumption and 10 aspects of automobile design and performance for 32 automobiles (1973–74 models).

Load library and dataset

library(plotly)

df <- mtcars
df <- within(df, {
  vs <- factor(vs, labels = c("V", "S"))
  am <- factor(am, labels = c("automatic", "manual"))
  cyl  <- ordered(cyl)
  gear <- ordered(gear)
  carb <- ordered(carb)
})

it shows the relation between miles/gallon(mpg), 1/4 mile tiem(qsec) between different transmission auto and manual(am) which in the category of carburetor numbers(carb).

fig <- df %>%
  plot_ly(
    x = ~qsec,
    y = ~mpg,
    size = ~hp,
    color = ~am,
    colors = c("red","black"),
    frame = ~carb,
    text = ~mpg,
    hoverinfo = "text",
    type = 'scatter',
    mode = 'markers'
  )

fig <- fig %>% layout(xaxis = list(type = "log"))
fig

plot_ly(df, x = ~mpg, y = ~hp, z = ~wt, type = 'scatter3d', 
        mode = 'lines+markers',line = list(width = 10, 
        color = ~gear, reverscale = FALSE))

Plotly’s R graphing library makes interactive, publication-quality graphs. It can be used to make a variety of graphics includeing: line plots, scatter plots, area charts, bar charts, error bars, box plots, histograms, heatmaps, subplots, multiple-axes, and 3D (WebGL based) charts.
